We assemble for a customer that is having an inconsistent low level analog interference we believe with the no clean flux residue from Alphas OM5100 solder paste. We are considering testing Amtechs 4300 water washable no clean paste. We will test bot

wlsmt: You’ve got to help us out here: * Why did you apply solder paste to capacitors prior to water washing the PCBA [where the caps were attached?]? * Did you reflow the Alpha WS-609? * How is the Alpha WS-820 involved in this? * Talk about the

Hi. Alpha metals recently informed us of: Alpha OM-565 low temp solder which they note is popular with pin-in-paste process of through hole parts so that we can solder inside of our SMT oven (1809EXL). We commonly use ROHS DSUB connectors (9 to 78

I recently purchased a cleaner. I have made great efforts to find a Flux that will not cause this closed loop cleaner to foam. The last was a Neutral WS flux from Alpha Metals but it still foams. This foaming is happening after wave solder.

We too had a problem with the WS609. We have since switched to Alpha's WS619 (same formula with an anti-foaming agent) This really helped but we still monitor flux application and try to minimize wherever possible. Chris

Dear Chris, I suppose that you may contact Alpha Metals or Cookson Semiconductor guys. They offer several types of no-clean flux for flip chip application. I hope it would not be too late. Kelvin
